摘　　要：目的:分析2012-2014年深圳市宝安区手足口病(HFMD)监测数据的季节性分布特征,为制定防治策略和提供控制措施提供参考。方法:采用Excel 2007软件,利用"传染病报告信息管理系统"中的监测数据,计算集中度和圆形分布指标,并进行统计学分析。结果:集中度(M)=0.408,圆形分布r=0.4028,平均角为ā=177.9°,可信区间为(100.63°,255.15°)(P<0.01)。3年数据每年平均角比较,差异有统计学意义(P<0.01)。结论:2012-2014年深圳市宝安区手足口病发病具有一定季节性,发病高峰时间为6月底,流行期为3月中旬至9月中旬,各年度流行期持续时间不同。Objective： To analyze the seasonal distribution characteristics of HMFD from 2012 to 2014 in Baoan District of Shenzhen City, providing a reference for making control strategy and measures.Method： By using the Excel 2007 software, the monitoring data from the infectous diseases reporting information management system were analyzed statically, to calculate the concentration degree and circular distribution index.Result： The concentration degree （M） was 0.408, the circular distribution r was 0.4028, average angle （6） was 177.9°, and the confidence interval was between 100.63° and 255.15°.There were significant differences in average angle among three years （ P〈0.01 ） .Conclusion： From 2012 to 2014 in Baoan District of Shenzhen City, HFMD has a certain seasonal distribution, the peak incidence is at the end of June, the epidemic time is from mid March to mid September.
